What is the main cause of ADHD?
Causes of ADHD
In addition to genetics, scientists are studying other possible causes and risk factors including: Brain injury. Exposure to environmental (e.g., lead) during pregnancy or at a young age. Alcohol and tobacco use during pregnancy.
Where does ADHD originate from?
In 1798, a Scottish doctor, Sir Alexander Crichton, noticed some people were easily distracted and unable to focus on their activities the way others could. He reported that these symptoms began early in life. That’s consistent with what we now call attention deficit hyperactivity disorder (ADHD).
What is the chemical imbalance that causes ADHD?
Biological: ADHD is associated with the way certain neurotransmitters (chemicals in the brain that help control behavior) work, especially dopamine and norepinephrine, and this difference causes changes in two different attentional networks of the brain — the default network, associated with automatic attention and the …
What is the science behind ADHD?
ADHD was the first disorder found to be the result of a deficiency of a specific neurotransmitter — in this case, norepinephrine — and the first disorder found to respond to medications to correct this underlying deficiency. Like all neurotransmitters, norepinephrine is synthesized within the brain.
Can ADHD go away?
Many children (perhaps as many as half) will outgrow their symptoms but others do not, so ADHD can affect a person into adulthood.
Does ADHD get worse with age?
Hormonal changes can cause ADHD symptoms to worsen, making life even more difficult for women. For men and women, aging can also lead to cognitive changes.
Who first diagnosed ADHD?

It is never too late to recognize, diagnose, and treat ADHD and any other mental health condition that can commonly occur with it.
What is wrong with an ADHD brain?
ADHD brains have low levels of a neurotransmitter called norepinephrine. Norepinephrine is linked arm-in-arm with dopamine. Dopamine is the thing that helps control the brain’s reward and pleasure center. The ADHD brain has impaired activity in four functional regions of the brain.
Does ADHD show up on an MRI?
No brain imaging modality — MRI, SPECT scan, T.O.V.A, or other — can accurately diagnose attention deficit hyperactivity disorder (ADHD or ADD).
Is ADHD a lack of serotonin?
Serotonin is another neurotransmitter implicated in ADHD. It influences mood, social behavior, sleep, and memory. Low levels of serotonin may impair these important functions.
Can a brain scan show ADHD?
Brain magnetic resonance imaging (MRI) can be used to identify people with attention-deficit/hyperactivity disorder (ADHD) from patients without the condition, according to a new study published in Radiology. Information from brain MRIs may also help to distinguish among subtypes of ADHD.
What does caffeine do to someone with ADHD?
Some studies have found that caffeine can boost concentration for people with ADHD. Since it’s a stimulant drug, it mimics some of the effects of stronger stimulants used to treat ADHD, such as amphetamine medications.
